Be it known that we, SAMUEL GLOVER and JOHN lVnsT, subjects of the King of Great Britain and Ireland, and residents of Olive Mount, St. Helens, in the county of Lan caster, England, and Alton Lodge, Park Crescent, Southport, in the county of Lancaster, England, respectively, have invented certain new and useful Improvements in Vertical Retorts for the Continuous Destructive Distillation of Carbonaceous Materials, of which the following is a specification.

This invention relates to vertical retorts for the continuous destructive distillation oi carbonaceous materials and more particularly to vertical retorts in which steam is ad mitted for the production of water gas in a known manner;

The object of the invention is to insure that the incandescent coke adjacent the point where the steam is injected into the retort shall be in a form to insure the rapid conversion of the steam into water gas.

The, invention com-prises the combination with a vertical retort and with a worm extractor adapted to en port the charge in the retort, of a chamber between the worm and the base of the retort proper, said chamber being of larger sectional plan area than the retort sothat the lateral support of the, coke from the retort is withdrawn, allowing the action of the rotating extractor to deflect and split up in said chamber the coke leaving the retort and means for passing steam into the coke in said chamber.

Referring to the accompanying sheet of ex lanatory drawings igure 1 is a sectional'elevation of part of a retort setting, the retorts in which are constructed in accordance with our invention.

Figure. 2 is a diagram to be hereinafter referred to.

In accordance with the illustrated appli cation of our invention, the base of each elliptical retort proper a is gradually widened at its lower end and between suchend and the worm or like extractor b by which the coke is discharged into the coke hopper (not shown), we provide an extension or chamber 0 which may widen gradually from the bottom of the elliptical retort tillit assumes the circular form of the part d where the upper end of the worm extractor b operates, thereby giving a much larger area for the distribution of the incandescent coke for the proper. and efiicient production of water gas from steam injected into the coke. The extension 0 may be built of suitable brickwork and may, if desired, be externally heated by one or more rows of combustion chambers. The coke issuing from the retort and supported at the base by the head of the worm extractor b has its lateral support removed and is deflected and evenly distributed in the widened extension chamber due to the action of the extractor as it rotates, the coke being rather brittle at this stage. the retort with its extension is therefore filled with lumps of incandescent coke of such dimensions that the steam injected in a known manner into the coke ho per (not shown) or into the extension cliamber o at 6 adjacent the worm extractor is brought into intimate contact therewith and has a very tortuous path as it travels upwards into the retort proper.

The extension chamber 0, before described, 5 by removing the lateral support for the coke leaving the retort, facilitates the proper distribution of the coke by the rotative effect of the worm.

Instead of widening the lower end of the retort proper as shown in Figure 1, we may continue the retort proper to its base as at present and provide the whole of the en- 1 largement in the chamber 0. The latter may be of cylindrical shape, if desired, instead of tapered or conical as illustrated.

In Figure 2, (1 indicates the plan dimension of the retort and o the plan dimension of the largest portion of the chamber a and of the art d.
